Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Only states the action without disclosing side effects, permissions needed, or return behavior. Annotations indicate non-read-only and non-destructive, but description adds no behavioral context beyond the basic action.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, front-loaded with verb, no wasted words. Efficiently conveys purpose and a key usage note.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Adequate for a simple creation tool with full schema and output schema. However, it lacks differentiation from sibling category tools and does not address error scenarios or required permissions, leaving some gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema covers all 4 parameters fully. Description adds minimal value beyond schema for the name parameter (sub-category naming). Baseline of 3 is appropriate given high schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states it creates a CMS post category with examples. The name and description distinguish it from sibling tools like create_product_category and create_service_category, even without explicit differentiation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides one guideline about sub-category naming (namespaced names) but does not explicitly compare to other category creation tools or state when to use this vs alternatives. Usage context is implied but not fully articulated.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
